- Session management must be enabled at the WAM level. For example
Begin_Com Role(*EXTENDS #PRIM_WAM) Layoutweblet('iiilay01') Sessionstatus(Active)
- At least one WebRoutine must have an Onentry() keyword of *sessionstatus_none. This enables the WebRoutine to execute, in order to activate a session.
- Other WebRoutines have a default Onentry() keyword of *sessionstatus_of_wam. If sessions are enabled for the WAM, then a session must be active for this WebRoutine to run.
- The WAM should contain an event handling routine for #com_owner.sessioninvalid that determines what happens when a session is invalid or expired. Usually this will transfer to the "login" WebRoutine to force a session to be established.
- Fields and lists to be stored on the server are defined via a special web_map. For example the following defines two working lists that are to be stored as persistent data:
Web_Map For(*none) Fields(#empsave #empdata) Options(*PERSIST)
The For(*none) keyword value means the fields are not mapped to and from the web page.

For more details refer to WAM Session Management.
- A second WAM will be developed that shares the session established by iiiSessionMng. This will demonstrate how more than one WAM may share a session and the persistent fields and lists which session management enables.
- WAMs share a session by having a BEGIN_COM statement that declares Sessionstatus active and has a common Session groupname. For example:
Begin_Com Role(*EXTENDS #PRIM_WAM) Layoutweblet('iiilay01') Sessiongroupname('MYSESSION') Sessionstatus(Active)

- WebRoutine showsave is called by a push button on the search web page. This second routine builds and displays a list from the saved list.
- The Clear Saved List pushbutton invokes the search WebRoutine to clear the saved list.
- Other functionality will be added in later steps.
To meet these objectives you will complete the following:
Step 1. Create Session Management 1 WAM
Step 2. Retrieve and Store Employee Details
Step 3. Create Session Management 2 WAM
Step 4. Test the Session Management Application
